I build my own tools, from a PS5 that runs language models to a Rust IDE that manages my servers. TAFE student, studying cybersecurity.

About

I'm studying a Certificate IV in Cyber Security at TAFE. Most of what I build starts because I want a tool that doesn't exist yet, so my projects cover systems programming, apps and the web.

Lately that means running AI models on my own hardware, locally and in the cloud, and building the software around them.

Projects

Most of these are open source. Nexus and its apps come with full setup docs.

Nexus

Open source GitHub ↗ Docs ↗ nexus.liamjc.dev ↗

An AI IDE and home-lab control room for my iPhone, Windows PC and NixOS machine, plus a web client. Every client shares one security policy: the Debian server is read-only, and AI agents can never write to it. It's open source, with guides for building the whole system yourself.

  1. NexusiOS ↗Swift · iPhone app with SSH, host metrics and AI chat
  2. NexusWindows ↗Rust · egui IDE with Codex and Claude Code
  3. NexusNix ↗Rust · the same app for NixOS, in progress
  4. NexusOnline ↗Astro · Cloudflare Workers and Access

Nexus Desktop rebuilt 1:1 for NixOS. It has the same IDE, AI agents and server dashboard as the Windows app, but works directly with NixOS itself. Both versions are written in Rust.

NexusAI

1.0.0GitHub ↗Docs ↗

Runs language models on a PS5 and serves them to my other devices through an OpenAI-compatible API, with its own dashboard on the console. Open source under GPL-3.0, with a model-control API for the Nexus gateway.
